NEST is a cryptocurrency that serves as the native asset of the NEST Protocol, a decentralized trading infrastructure called the martingale network. The NEST Protocol uses smart contracts to eliminate market markers and LPs, providing traders with infinite liquidity through risk sharing. The NEST Protocol consists of three modules: NEST Oracle, NEST Assets, and NESTcraft. NEST Oracle provides decentralized on-chain prices, while NEST Assets generate and burn currency units for martingale transactions on NEST. NESTcraft converts various on-chain random sources into a super martingale function library, providing customizable martingale trading options. The NEST Protocol can be used for various purposes, including decentralized contract exchanges, financial derivatives supermarkets, on-chain and off-chain risk hedging, the economic framework of Metaverse and GameFi, lottery, prop synthesis, and others.
